My tabs keep disappearing.

My last update was 4/21. Since then my tabs are disappearing from view when I open multiple pages. If I move my cursor to the top of the page, they reappear. I am wondering if this was part of the update? It temporarily allows you to view a bit more of the page I am viewing, but if this is supposed to be an advantage...it is NOT. I like to be able to see what tabs I have open and not have to scroll to the top of the page every time. Please help me correct or change this...thank you.

Firefox might be in full screen view. The F11 key switches between normal and full screen views.

It should not get stuck that way... If you find you have to keep switching out of full screen view, the file that stores window dimensions might have become corrupted. You can rename the file to resolve that issue, but this also may affect which bars are shown (for example, if you like using the classic menu bar, you may need to turn that back on). Here's how:

Open your current Firefox settings (AKA Firefox profile) folder using either

  • "3-bar" menu button > "?" button > Troubleshooting Information
  • (menu bar) Help > Troubleshooting Information
  • type or paste about:support in the address bar and press Enter

In the first table on the page, click the "Show Folder" button. This should launch a new window listing various files and folders in Windows Explorer.

Leaving that window open, switch back to Firefox and Exit, either:

  • "3-bar" menu button > "power" button
  • (menu bar) File > Exit

Pause while Firefox finishes its cleanup, then rename xulstore.json to something like xulstore.old. If you see a file named localstore.rdf, rename that one to localstore.old.

Start Firefox back up again. Do windows display normally again?
